10 (0M rah/01% it may concern.-

Be it known that I, CARL HERMANN R0B- ERT ScHwARz, a citizen of the German Empire, and a resident of Hamburg, Germany, have invented certain new and useful Improvements in Pile-Driving Machines, of which the following is a specification.

This invention relates to a pile-driving ma chine which can be used for driving vertical or inclined piles arranged in straight lines, as well as for operating in corners and along an gular lines.

Although machines of a similar nature have been used in which the runner-beam or gib is capable of being tipped forward or backward, while others are specially de signed for use in angular corners, none has been hitherto constructed for the combined uses aforesaid. For this purpose I arrange f the frame so as to enable the race of the ram or hammer to be placed vertically or in a forwardly or rearwardly inclined position, while,

moreover, the base is fitted with a front supf porting sleeper composed of three parts hinged together, so that each hinged end piece thereof can be turned or folded back, as may be necessary to enable the machine to work in corners.

The invention is shown in the accompanying drawings, in which I Figure 1 is a side elevation of the machine for vertical driving. Fig. 2 is a similar view, but showing the race-gib in an inclined position and the hinged portions of the front sleeper turned back. Figs. 3 and 4 are plans of the base portions of the frame with the upper parts removed therefrom. Fig. 5 is a front elevation of the machine with the hinged sleeper portions turned back. Fig. 6 is a plan and partial section of a portion of the machine.

The race-gib a is hinged to the base and secured at its upper end by the front ties b and rear ties c. The latter are perforated at the lower end and adjustably secured in perforated bars d by bolts d. The front ties b are similarly adjustable by means of guides t, bars a, and bolts 6, the bars 6 being hinged by bolts 6 to lugs e on the sleeper ends f. The latter are hinged by bolts h to the central portion to in such a manner as to be capable of being turned rearward, and in order to permit the ties I) to follow the movement of the ends f the lugs 6 are secured to such ends by vertical bolts g. The frame is further strengthened by hinged arms 7c and m, secured to the ties b and connected with the gib by the bolts "L and], respectively, while crossbars at and 0 form a detachable connection between the front struts b and rear struts c for the removal of the latter when turning back the sleeper ends To enable the bars a to readily slide in the guide t, it is necessary to curve the coacting parts, as well as the ends of the struts I), both in the forward direction, as also sidewise, as shown in Fig. 5.

For the purpose of securing the sleeper ends in their straight and in their folded position safety-bolts r are provided. They may be further secured by hooks g, held by eyes in the base and entering holes in the end pieces The arms 76 and m are also held in position by safety-bolts r. This improved construction-permits of the pile-driving machine being caused to work along a straight line upon vertical or inclined piles and also in or round corners.

What I claim is- 1. A pile-driving machine with movable gib, provided with a divided front sleeper whose outer portions f are hinge-jointed to the middle portion w and to front ties b so that by turning back the outer sleeper por ti ons, the machine canbe used in corners, as set forth.

2. A pile-driver provided with a pivoted gib, a pair of hinged sleepers, bars pivoted to the sleepers, and braces adjustably secured to the bars, substantially as specified.

8. A pile-driver provided with a pivoted gib, a pair of hinged sleepers, and pivoted braces adjustably secured to the sleepers, substantially as specified.
